Answer:
Year→
Section ↓ |
2014 | 2015 | 2016 | Total |
Grocery | 625000 | 675000 | 653000 | 1953000 |
Vegetables | 220000 | 242000 | 210000 | 672000 |
Medicines | 188000 | 175000 | 165000 | 528000 |
Textiles | 483000 | 536000 | 612000 | 1631000 |
Novelties | 94000 | 143000 | 131000 | 106000 |
Total | 1610000 | 1771000 | 1771000 | 5152000 |
Working notes:
2014-
We know,
Total sales = Grocery + Vegetables + Medicines + Textiles + Novelties
Assume the total sales to be x and textiles to be 30% of x.
Now, we solve for x,
Thus, the total sales is 1610000 and textiles will be 30% of x, i.e. 483000.
2015-
Total sales = 10% of x + x
or, Total sales = 161000 + 1610000 = 1771000
Grocery = 8% of 625000 + 625000 = 50000 + 625000 = 675000
Vegetables = 10% of 220000 + 220000 = 22000 + 220000 = 242000
Medicines dropped by 12000, so medicines = 175000
2016-
Total sales = 1771000
Grocery fell by 22000, so grocery = 653000
Vegetables fell by 32000, so vegetables = 210000
Medicines fell by 10000, so medicines = 165000
Novelties fell by 12000, so novelties = 131000
